Hitachi W6VB3SD 2,600-RPM Collated Screw Driving System Get it now!

This bit and the Hitachi "superdriver" collated screwdriver system sucks.
I paid over $300.00 for the superdriver system so I could drive screws into cement underlayment board for ceramic tile, without being on my hands & knees. For an additional $ 150.00 I purchased 3,000 collated screws with the LOZ screw head, because they weren't supposed to strip, mis-feed, etc. "like the other brands".

The Hitachi superdriver LOX screws are only available via the internet, so you have to plan your job in advance
and buy more collated screws then you think you'll need. Cement board screws are $50.00 a thousand.

Long story short, the LOX bit fell apart after 2,000 screws.
About 200 screws mis-fed and fell out of the strip before they could be used, once the strip location is used, you can't reinsert the unused screw.
Another 100 or so screws didn't seat flush like they were supposed too. And needed to be driven flush with another sheetrock screw gun.
A second attempt to drive the screws flush using a stand square head bit, usually strips out the LOX head.
The LOX screws strip out four times as much as standard square head screws (I love standard square head drive screws)

A new bit is only available via the Internet, so I was stuck with an unfinished job and 900 screws I couldn't use.
I tried to purchase Senco phillips head screws to finish the job, since a phillips head bit is included with the gun. Senco has gone bankrupt, so their screws are no longer available.
I had to borrow a sheetrock screw gun, purchase individual screws and manually insert 600 screws one at a time to finish the job.

Documentation I've read while researching my purchase of this gun implys the extention can be removed, allowing the screwdriver gun to be used without the extention. The included and Hitachi website documentation is extremely POOR. It states areas should be lubed, but its up to the user to figure out where lube is needed.
No part numbers are shown for the bits (which break after 2,000 screws).
The bits themselves aren't shown anywhere in the documentation either.
None of the documentation shows the screwgun and the extention in a combined fashion.
Nor does it show how to disassamble/assamble the extention to the gun itself.

When it works properly (about 80% of the time), it's great, otherwise it sucks.
To say it's BADLY OVER PRICED is an under statement.

I'm only buying a replacemnt LOX bit so I can use the 900 or so screws I now have left over on some other future project.
I wouldn't buy it again.
